okay had a CEL sometimes when i first got the car, (92SC4) that would seem to be linked with firing of the coil... or maybe firing of one of the wires on the cap... sometimes when i accelerate the CEL light would come on and increase in speed of flashing with RPM of the engine. do you guys understand what i mean? i did a complete tune up including compression check on all eight cyls. replaced the plugs with NGK GP, wires, caps, and rotors. and didnt get the light again till yesterday... its still flashes with the speed of the motor. figured it was a bad plug or maybe its misfiring on the cap, so i changed it all.... any ideas what causes this. havent pulled OBDI codes yet, but thats my next step. any ideas?

 

come on someone help me please.

 

sorry, cant help u. my CEL turns on for about 10 mins to a day and turns off for about 2 days. Weird as hell... its been doin this for about 2 months and I still dont know what the problem is... good luck

 

Pull the codes and you will know the problem. Or at least get you in the right direction.

 

how do i pull codes

 

okay i pulled codes... but got no codes!!!! just OD codes. code 63 for the transmission! no engine codes.... but when i run the car, if i hit the accelerator i get the engine light.

 

same here..mine will shut off after 2 ro 3 days, and if i get on the gas hard, it kicks on, stays for a few days, then repeats its self...and i get no codes

 

how did you pull the codes? did you do the self diagnose with the jumper wire?

 

yeah plugged in a wire to TE1 to E1 on the diagnostic terminal in the engine bay and turned key to on position... only thing that came on is the OD light giving me a code 63 for the solenoids.

 

it only comes on when i accelerate or give it gas... and it seems to be in time with the firing of a coil or something.......... it flashes faster with the speed of the motor.

 

same here, but i didnt get any codes
